Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector device for cleaning an endoscope conduit which is connected to a mouthpiece on an endoscope side.

When cleaning the inside of an endoscope duct, it has been considered to connect connectors of liquid feeding tubes to various cylinders of the operating section and to send b°C purified liquid into the endoscope duct for cleaning. In this case, the conventionally considered connector was of a type in which the connector was screwed into the connector using a threaded portion formed on the inner circumferential surface of the cylinder mouthpiece. 1. The tip of the connector is inserted into the inner hole of the base, and an O ll song is fitted around the outer circumference of the tip of the connector, and this O-ring is inserted into the inner periphery of the inner hole of the base. It was a connection method that ensured that it was in close contact with the surface to ensure water retention.

Therefore, in the structure of this conventional connector, since the tip of the connector is inserted into the inner hole of the base,
This has been a problem because there are many parts of the inner hole that do not come into contact with the cleaning liquid, and many parts of the inner surface are left unwashed and unwashed.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to: When a connector of a liquid sending tube is connected to the mouthpiece of a conduit, the portion that remains unwashed in the inner hole of the mouthpiece. An object of the present invention is to provide a connector body for cleaning an endoscope conduit, which can eliminate the problem and improve the cleaning effect.

Hereinafter, each embodiment of the present invention will be described in sequence based on the drawings.
